How do I get the current absolute URL in Ruby on Rails?

For Rails 3.2 or Rails 4+

You should use request.original_url to get the current URL. Source code on current repo found here.

This method is documented at original_url method, but if you're curious, the implementation is:

def original_url
  base_url + original_fullpath
end

For Rails 3:

You can write "#{request.protocol}#{request.host_with_port}#{request.fullpath}", since request.url is now deprecated.

For Rails 2:

You can write request.url instead of request.request_uri. This combines the protocol (usually http://) with the host, and request_uri to give you the full address.

I think that the Ruby on Rails 3.0 method is now request.fullpath.

You could use url_for(only_path: false)

DEPRECATION WARNING: Using #request_uri is deprecated. Use fullpath instead.

If you're using Rails 3.2 or Rails 4, you should use request.original_url to get the current URL.

Documentation for the method is at http://api.rubyonrails.org/classes/ActionDispatch/Request.html#method-i-original_url, but if you're curious, the implementation is:

def original_url
  base_url + original_fullpath
end

EDIT: This is still the case for Rails 7 (Docs).

You can add this current_url method in the ApplicationController to return the current URL and allow merging in other parameters

# https://x.com/y/1?page=1 
# + current_url( :page => 3 )
# = https://x.com/y/1?page=3
def current_url(overwrite={})
    url_for :only_path => false, :params => params.merge(overwrite)
end

Example Usage:

current_url --> http://...
current_url(:page=>4) --> http://...&page=4

For Ruby on Rails 3:

request.url
request.host_with_port

I fired up a debugger session and queried the request object:

request.public_methods

In Ruby on Rails 3.1.0.rc4:

 request.fullpath

I needed the application URL but with the subdirectory. I used:

root_url(:only_path => false)

 url_for(params)

And you can easily add some new parameter:

url_for(params.merge(:tag => "lol"))

I think request.domain would work, but what if you're in a sub directory like blah.blah.com? Something like this could work:

<%= request.env["HTTP_HOST"] + page = "/" + request.path_parameters['controller'] + "/" + request.path_parameters['action'] %>

Change the parameters based on your path structure.

Hope that helps!

It looks like request_uri is deprecated in Ruby on Rails 3.

Using #request_uri is deprecated. Use fullpath instead.

Using Ruby 1.9.3-p194 and Ruby on Rails 3.2.6:

If request.fullpath doesn't work for you, try request.env["HTTP_REFERER"]

Here's my story below.

I got similar problem with detecting current URL (which is shown in address bar for user in her browser) for cumulative pages which combines information from different controllers, for example, http://localhost:3002/users/1/history/issues.

The user can switch to different lists of types of issues. All those lists are loaded via Ajax from different controllers/partials (without reloading).

The problem was to set the correct path for the back button in each item of the list so the back button could work correctly both in its own page and in the cumulative page history.

In case I use request.fullpath, it returns the path of last JavaScript request which is definitely not the URL I'm looking for.

So I used request.env["HTTP_REFERER"] which stores the URL of the last reloaded request.

Here's an excerpt from the partial to make a decision

- if request.env["HTTP_REFERER"].to_s.scan("history").length > 0
  - back_url = user_history_issue_path(@user, list: "needed_type")
- else
  - back_url = user_needed_type_issue_path(@user)
- remote ||= false
=link_to t("static.back"), back_url, :remote => remote

This works for Ruby on Rails 3.0 and should be supported by most versions of Ruby on Rails:

request.env['REQUEST_URI']

None of the suggestions here in the thread helped me sadly, except the one where someone said he used the debugger to find what he looked for.

I've created some custom error pages instead of the standard 404 and 500, but request.url ended in /404 instead of the expected /non-existing-mumbo-jumbo.

What I needed to use was

request.original_url

If by relative, you mean just without the domain, then look into request.domain.

You can use the ruby method:

:root_url

which will get the full path with base url:

localhost:3000/bla

(url_for(:only_path => false) == "/" )? root_url : url_for(:only_path => false)

In Rails 3 you can use

request.original_url

http://apidock.com/rails/v3.2.8/ActionDispatch/Request/original_url

you can use any one for rails 3.2:

request.original_url
or
request.env["HTTP_REFERER"]
or
request.env['REQUEST_URI']

I think it will work every where

"#{request.protocol}#{request.host}:#{request.port}#{request.fullpath}"

Rails 4.0

you can use request.original_url, output will be as given below example

get "/articles?page=2"

request.original_url # => "http://www.example.com/articles?page=2"

You can either use

request.original_url 

or

"#{request.protocol}#{request.host_with_port}" 

to get the current URL.

For Rails 3.2 or Rails 4 Simply get in this way "request.original_url" Reference: Original URL Method

For Rails 3 As request.url is deprecated.We can get absolute path by concatenating

"#{request.protocol}#{request.host_with_port}#{request.fullpath}"

For Rails 2

request.url

if you want to be specific, meaning, you know the path you need:

link_to current_path(@resource, :only_path => false), current_path(@resource)

For rails 3 :

request.fullpath

request.env["REQUEST_URI"]

works in rails 2.3.4 tested and do not know about other versions.

To get the request URL without any query parameters.

def current_url_without_parameters
  request.base_url + request.path
end

You can set a variable to URI.parse(current_url), I don't see this proposal here yet and it works for me.

You can use:

request.full_path

or

request.url

Hopefully it will resolve your problem.

Cheers

To get the absolute URL which means that the from the root it can be displayed like this

<%= link_to 'Edit', edit_user_url(user) %>

The users_url helper generates a URL that includes the protocol and host name. The users_path helper generates only the path portion.

users_url: http://localhost/users
users_path: /users
